THIS   AMENDED AND RESTATED  AGREEMENT  made and entered into as of the 29th day
       of  October  1996,  by and  among  The  Lehigh  Group  Inc.,  a  Delaware
       corporation  ("Lehigh"),  Lehigh Management Corp., a Delaware corporation
       and a  wholly-owned  subsidiary  of Lehigh  ("Newco")  and First  Medical
       Corporation, a Delaware corporation ("FMC"). Unless the context indicates
       otherwise, all references herein to Lehigh or FMC refer to Lehigh and FMC
       and their respective wholly owned subsidiaries.

                          W I T N E S S E T H  T H A T:

                                R E C I T A L S:

     (A) Lehigh has recently organized Newco for the purpose of merging with and
into FMC on the terms and  conditions set forth herein and with the effect that,
as a result thereof,  the present  stockholders of Lehigh will upon consummation
of the Merger hold four percent of the total equity of Lehigh on a fully diluted
basis.

     (B) Simultaneously  with the execution and delivery of this Agreement,  FMC
is lending to Lehigh the sum of $300,000  and, in  evidence  thereof,  Lehigh is
delivering to FMC a debenture in the form annexed hereto as Exhibit A.

     (C) It is intended that the  transactions  contemplated  by this  Agreement
shall constitute a "reorganization"  within the meaning of Section 368(a) of the
Internal Revenue Code of 1986, as amended.

     NOW, THEREFORE, in consideration of the mutual covenants and agreements and
the benefits to be realized by each of the parties,  the parties hereto agree as
follows:

     1. THE MERGER

     (a) On the  Closing  Date,  Newco  shall be  merged  with and into FMC (the
"Merger") in accordance  with the provisions of the General  Corporation  Law of
the State of Delaware (the "DGCL").  FMC shall be the surviving  corporation  of
the Merger,  shall be a wholly-owned  subsidiary of Lehigh and shall continue to
be governed by the laws of Delaware. Immediately prior to the Effective Time (as
hereinafter  defined) there shall be filed with the Delaware  Secretary of State
an amendment to the Certificate of  Incorporation of Lehigh providing for "blank
check" preferred stock and a Certificate of Designation establishing a series of
1,037,461  shares of preferred  stock to be designated  the Series A Convertible
Preferred Stock, $.001 par value, of Lehigh (the "Lehigh Preferred Stock"), each
share of which shall be  convertible  at any time by the holder thereof into 250
shares of the common  stock,  $.001 par value,  of Lehigh  (the  "Lehigh  Common
Stock") and each share of which shall be entitled to 250 votes,  voting together
with  the  Lehigh  Common  Stock,   on  all  matters  subject  to  the  vote  of
stockholders.  Upon the  effectiveness  of the  Merger,  and by  virtue  thereof
without any further action by Lehigh, FMC or any of their stockholders:  (i) any
and all shares of the Lehigh Common Stock held by


                                       A-1




FMC immediately prior to the Effective Time shall be cancelled;  (ii) each other
share of the Lehigh Common Stock issued and outstanding immediately prior to the
Effective  Time shall  remain  issued and  outstanding;  and (iii) each share of
common stock,  $.01 par value, of FMC (the "FMC Common Stock") shall cease to be
outstanding  and shall be converted  into (A) 1,127.675  shares of Lehigh Common
Stock and (B) 103.7461 shares of Lehigh Preferred Stock.

     (b) Certificates representing shares of FMC Common Stock shall be exchanged
for certificates of Lehigh Common Stock and Lehigh Preferred Stock as follows:

          (i) After the  Effective  Time,  certificates  evidencing  outstanding
     shares of FMC Common Stock shall  evidence the right of the holder  thereof
     to receive  certificates  representing  1,127.675  shares of Lehigh  Common
     Stock and 103.7461  shares of Lehigh  Preferred Stock for each share of FMC
     Common  Stock.  Each  holder of FMC Common  Stock,  upon  surrender  of the
     certificates which prior thereto represented shares of FMC Common stock, to
     a trust  company to be designated by Lehigh which shall act as the exchange
     agent (the "Exchange  Agent") for such  stockholders to effect the exchange
     of certificates  on their behalf,  shall be entitled upon such surrender to
     receive in exchange therefor a certificate or certificates representing the
     number of whole shares of Lehigh  Common Stock and Lehigh  Preferred  Stock
     into which the shares of FMC Common Stock  theretofore  represented  by the
     certificate or certificates so surrendered shall have been converted. Until
     so surrendered,  each such outstanding certificate for shares of FMC Common
     Stock shall be deemed,  for all corporate purposes including voting rights,
     subject to the further  provisions  of this Section  1(b),  to evidence the
     ownership of the whole shares of Lehigh  Common Stock and Lehigh  Preferred
     Stock into which such shares have been converted.

          (ii) No certificate  representing a fraction of Lehigh Common Stock or
     Lehigh  Preferred  Stock will be issued and no right to vote or receive any
     distribution  or any  other  right of a  stockholder  shall  attach  to any
     fractional  interest of Lehigh  Common Stock or Lehigh  Preferred  Stock to
     which any holder of shares of FMC Common Stock would  otherwise be entitled
     hereunder.

          (iii) If any  certificate  for whole shares of Lehigh  Common Stock or
     Lehigh  Preferred  Stock is to be issued in a name other than that in which
     the certificate surrendered in exchange therefor is registered, it shall be
     a condition of the issuance  thereof that the  certificate  so  surrendered
     shall be properly endorsed and otherwise be in proper form for transfer and
     that the person  requesting  such  exchange pay to the  Exchange  Agent any
     transfer or other taxes required by reason of the issuance of  certificates
     for shares of Lehigh  Common  Stock or Lehigh  Preferred  Stock in any name
     other than that of the registered holder of the certificate surrendered.

          (iv) At the Effective Time, all shares of FMC Common Stock which shall
     then  be held in its  treasury,  if any,  shall  cease  to  exist,  and all
     certificates representing such shares shall be cancelled.

     (c) Lehigh and FMC shall each submit this Agreement to its stockholders for
approval in  accordance  with the DGCL,  at an annual or special  meeting of the
stockholders  (the  "Meeting")  called  and  held on a date to be fixed by their
respective  Boards of  Directors  and shall use their best  efforts to hold such
meeting on or before May 15, 1997 or as soon thereafter as practical.

     (d)  Lehigh  and FMC  shall  each  use  its  best  efforts  to  obtain  the
affirmative  vote of  stockholders  required to approve this  Agreement  and the
transactions  contemplated  hereby,  and  will  recommend  to  their  respective
stockholders the approval of the Merger, subject however, in the case of

                                       A-2




each company's Board of Directors,  to its fiduciary obligation to stockholders.
Lehigh  shall mail to all of its  stockholders  entitled  to vote at and receive
notice of such meeting the material required in accordance with the Registration
Statement and Prospectus provisions specified in paragraph 9 hereof.

     (e) On or before the date of the  Meeting,  the Board of Directors of Newco
shall duly approve this  Agreement  and Lehigh,  as sole  stockholder  of Newco,
shall duly approve this Agreement and the transactions contemplated hereby.

     (f)  Following  the approval of the Merger by the  stockholders  of Lehigh,
Newco and FMC, a Certificate of Merger  containing the  information  required by
applicable law shall be executed by the appropriate officers of FMC and Newco.

     (g)  Notwithstanding any other provision of this Agreement to the contrary,
if Lehigh  receives a proposal for a business  combination  with any other party
which is more favorable to Lehigh or its  stockholders  than the terms set forth
in this Agreement (an "Alternate Proposal") at any time prior to consummation of
the  Merger,   Lehigh  shall  be  entitled  to  pursue  and/or  consummate  such
transaction  free of any  obligation to FMC under or pursuant to this  Agreement
except for those obligations set forth in Section 17 hereof.

     2. CLOSING; EFFECTIVE TIME

     (a) The closing of all the transactions  contemplated hereby (herein called
the  "Closing" or the "Closing  Date") shall occur at a date and place  mutually
agreed between the parties and on a date within fifteen (15) business days after
all of the of the conditions  described in paragraphs 14 and 15 hereof have been
satisfied  or,  to  the  extent  permitted  by  paragraph  16(c)  hereof,  their
satisfaction has been waived.  Lehigh, Newco and FMC will use their best efforts
to obtain the  approvals  specified  in  paragraph 8 hereof and any other of the
consents,  waivers,  or  approvals  necessary or  desirable  to  accomplish  the
transactions  contemplated  by this  Agreement.  All  documents  required  to be
delivered  by  each  of the  parties  hereto  shall  be  duly  delivered  to the
respective recipient thereof at or prior to the Closing.  Without the consent of
FMC and Lehigh to extend such date, the Closing Date shall be no later than June
30, 1997, and if it is delayed  beyond said date, or extended date,  then either
party  shall have the right to  terminate  this  Agreement  upon  notice to that
effect.

     (b) At the Closing,  Lehigh,  Newco and FMC shall  jointly  direct that the
Certificate  of Merger be duly filed,  and in accordance  with such direction it
shall be filed, in the Offices of the Secretary of State of Delaware so that the
Merger  shall be  effective  on the Closing  Date.  The time at which the Merger
becomes effective is referred to herein as the "Effective Time."

     3. LISTING

     At a time mutually  agreed to by Lehigh and FMC, but in no event later than
the date following the approval of  stockholders  of both Lehigh and FMC, Lehigh
agrees,  at its  expense,  to  apply  for and use its  best  efforts  to  obtain
additional  listings  on the New York  Stock  Exchange,  subject  to  notice  of
issuance,  of  the  shares  of  Lehigh  Common  Stock  to be  delivered  to  FMC
stockholders  in the  Merger.  FMC  agrees  to  render  assistance  to Lehigh in
obtaining such listing, including the furnishing of such financial statements as
Lehigh may reasonably request.


                                       A-3




     4. INVESTIGATION BY THE PARTIES

     Lehigh  and FMC  acknowledge  that they have made or caused to be made such
investigation  of the  properties of the other and its  subsidiaries  and of its
financial  and legal  condition  as the party  making such  investigation  deems
necessary or  advisable to  familiarize  itself with such  properties  and other
matters.  Lehigh and FMC each agree that if  matters  come to the  attention  of
either party requiring additional due diligence, each agrees to permit the other
and its  authorized  agents  or  representatives  to  have,  after  the  date of
execution  hereof,  full  access  to its  premises  and to all of its  books and
records at reasonable  hours, and its subsidiaries and officers will furnish the
party making such investigation with such financial and operating data and other
information  with  respect  to  the  business  and  properties  of  it  and  its
subsidiaries  as the party  making  such  investigation  shall from time to time
reasonably  request.  No  investigation  by  Lehigh  or  FMC  shall  affect  the
representations  and  warranties of the other and each such  representation  and
warranty shall survive any such investigation. Each party further agrees that in
the  event  the  transactions  contemplated  by  this  Agreement  shall  not  be
consummated, it and its officers, employees, accountants,  attorneys, engineers,
authorized agents and other  representatives will not disclose or make available
to any other person or use for any purpose unrelated to the consummation of this
Agreement any  information,  whether  written or oral, with respect to the other
party and its subsidiaries or their business which it obtained  pursuant to this
Agreement.  Such information shall remain the property of the party providing it
and shall not be reproduced or copied without the consent of such party.  In the
event  that  the  transactions  contemplated  by  this  Agreement  shall  not be
consummated,  all such  written  information  shall  be  returned  to the  party
providing it.

     5. "AFFILIATES" OF FMC

     Each stockholder of FMC who is, in the opinion of counsel to Lehigh, deemed
to be an "affiliate" of FMC as such term is defined in the rules and regulations
of the Securities and Exchange  Commission  under the Securities Act of 1933, as
amended  (hereinafter  called the "1933  Act"),  is listed on a  Schedule  to be
delivered to Lehigh within 20 days hereof, and will be informed by FMC that: (i)
absent an applicable  exemption  under the 1933 Act, the shares of Lehigh Common
Stock to be received by such "affiliate" and owned  beneficially on consummation
of the transactions  contemplated  hereunder may be offered and sold by him only
pursuant to an effective  registration  statement under the 1933 Act or pursuant
to the provisions of paragraph (d) of Rule 145  promulgated  under the 1933 Act;
(ii) Rule 145 restricts the amount and method of subsequent dispositions by such
"affiliate"  of  such  shares  and  (iii)  a  continuity  of  interests  by  the
"affiliate" must be maintained.  Prior to the Closing Date, FMC agrees to obtain
from each  "affiliate"  an agreement to the effect that such  affiliate will not
publicly sell any of such shares unless a registration  statement under the 1933
Act with respect thereto is then in effect,  or such  disposition  complies with
paragraph  (d)  of  Rule  145  promulgated   under  the  1933  Act,  or  counsel
satisfactory  to Lehigh has  delivered  a written  opinion to Lehigh and to such
"affiliate" that  registration  under the 1933 Act is not required in connection
with such disposition.

     6. STATE SECURITIES LAWS

     Lehigh  will take such steps as may be  necessary  to comply with any state
securities or so-called  Blue Sky laws  applicable to the actions to be taken in
connection with the Merger and the delivery by Lehigh to FMC stockholders of the
shares of  Lehigh  Common  Stock  and  Lehigh  Preferred  Stock to be  delivered
pursuant  to  this   Agreement.   Costs  and  expenses  of  any  such   Blue-Sky
qualifications shall be borne by Lehigh.

this Section 9, but not be limited to,  attorneys'  fees and any and all expense
whatsoever  incurred  in  investigating,  preparing,  or  defending  against any
litigation,  commenced or  threatened,  or any claim  whatsoever and any and all
amounts paid in  settlement  of any claim or  litigation)  as and when  incurred
arising out of, based upon,  or in connection  with (i) any untrue  statement or
alleged  untrue  statement  of a material  fact made by the party  against  whom
indemnification is sought and contained (1) in any  Prospectus/Proxy  Statement,
the Registration Statement, or Proxy Statement (as from time to time amended and
supplemented) or any amendment or supplement  thereto; or (2) in any application
or other document or  communication  (in this Section 9  collectively  called an
"application")  executed by or on behalf of either  party or based upon  written
information  filed in any  jurisdiction in order to qualify the shares of Lehigh
Common  Stock and Lehigh  Preferred  Stock to be issued in  connection  with the
Merger and the shares of Lehigh  Common Stock  issuable  upon  conversion of the
Lehigh  Preferred Stock under the "Blue Sky" or securities laws thereof or filed
with the Securities and Exchange Commission or any securities  exchange;  or any
omission  or alleged  omission  to state a material  fact  required to be stated
therein or necessary to make the statements therein not misleading;  unless such
statement or omission was made in reliance upon and in  conformity  with written
information   furnished  to  the  indemnifying  party  from  the  party  seeking
indemnification  expressly for inclusion in any Prospectus/Proxy  Statement, the
Registration  Statement,  or Proxy  Statement,  or any  amendment or  supplement
thereto,  or in any  application,  as the case may be,  or (ii)  any  breach  of
representation,  warranty,  covenant,  or agreement contained in this Agreement.
The foregoing  agreement to indemnify shall be in addition to any liability each
party may otherwise have, including liabilities arising under this Agreement. If
any action is brought  against  either party or any of its officers,  directors,
partners,  employees, agents, or counsel ( an "indemnified party") in respect of
which indemnity may be sought pursuant to the foregoing paragraph,


                                       A-6




such  indemnified  party or parties shall  promptly  notify the other party (the
"indemnifying  party") in writing of the  institution  of such  action  (but the
failure to so notify shall not relieve the indemnifying party from any liability
it may have other than  pursuant to this  Paragraph  9(b)) and the  indemnifying
party shall promptly assume the defense of such action, including the employment
of counsel and payment of expenses  (satisfactory to such  indemnified  party or
parties).  Such indemnified  party or parties shall have the right to employ its
or their own counsel in any such case, but the fees and expenses of such counsel
shall  be at the  expense  of such  indemnified  party  or  parties  unless  the
employment  of such  counsel  shall  have  been  authorized  in  writing  by the
indemnifying  party  in  connection  with  the  defense  of such  action  or the
indemnifying party shall not have promptly employed counsel satisfactory to such
indemnified  party or parties to have  charge of the  defense of such  action or
such indemnified party or parties shall have reasonably concluded that there may
be one or more legal  defenses  available to it or them or to other  indemnified
parties which are different  from or additional to those  available to the other
party in any of  which  events  such  fees  and  expenses  shall be borne by the
indemnifying party and the indemnifying party shall not have the right to direct
the  defense  of such  action  on behalf of the  indemnified  party or  parties.
Anything in this  paragraph to the contrary  notwithstanding,  the  indemnifying
party  shall  not be  liable  for any  settlement  of any such  claim or  action
effected without its written consent.

     10. COOPERATION BETWEEN PARTIES

     FMC and  Lehigh  shall  fully  cooperate  with each  other  and with  their
respective  counsel and  accountants in connection with any steps required to be
taken  as  part  of  their  obligations  under  this  Agreement,  including  the
preparation  of  financial  statements  and  the  supplying  of  information  in
connection  with the  preparation  of the  Registration  Statement and the Proxy
Statement.

     11. REPRESENTATIONS OF LEHIGH

     (c) The shares of Lehigh Common Stock and Lehigh  Preferred Stock which are
to be issued and delivered to the FMC stockholders pursuant to the terms of this
Agreement,  when so issued and delivered,  will be validly authorized and issued

filed with the  Securities  and Exchange  Commission for the year ended December
31, 1995 which contains  consolidated  balance sheets of Lehigh and subsidiaries
as of  December  31, 1995 and 1994 and the related  consolidated  statements  of
operations,  stockholders  equity (deficit) and cash flows for each of the three
years in the period ended December 31, 1995 audited by BDO Seidman,  LLP. Lehigh
has also furnished FMC with unaudited  financial  statements as of June 30, 1996
as set  forth  in its Form  10-Q as  filed  with  the  Securities  and  Exchange
Commission.   All  of  the  above  financial   statements   present  fairly  the
consolidated  financial  position of Lehigh and its  subsidiaries at the periods
indicated,  and the  consolidated  results of operations  and cash flows for the
periods  then ended.  The interim  financial  statements  have been  prepared in

basis,  and in the opinion of Lehigh  include  all  adjustments  (consisting  of
normal  recurring  accruals)  necessary for a fair  presentation of such interim
period.  Since June 30,  1996 there has been no material  adverse  change in the
assets or liabilities  or in the business or condition,  financial or otherwise,
of Lehigh or its consolidated subsidiaries, and no change except in the ordinary
course of business or as contemplated by this Agreement.

     (e) Except as disclosed in the public  filings of Lehigh and except for the
lawsuit  filed by  Southwicke  Corporation  a copy of the  complaint in which is

action or other proceeding before any court or administrative  agency or (ii) to
the knowledge of Lehigh,  has been charged with, or is under  investigation with
respect to, any charge  concerning any presently  pending material  violation of

                              THE LEHIGH GROUP INC.

                         (Pursuant to Section 151 of the
                General Corporation Law of the State of Delaware)


     The Lehigh  Group Inc., a  corporation  organized  and  existing  under the
General  Corporation  Law of the State of Delaware (the  "Corporation"),  hereby
certifies that the following resolution was adopted by the Board of Directors of
the Corporation:

     RESOLVED,  that,  pursuant to the authority expressly granted to and vested
in the Board of Directors of the  Corporation  (the "Board of Directors") by the
provisions  of  the  Certificate  of   Incorporation  of  the  Corporation  (the
"Certificate of Incorporation"),  there hereby is created,  out of the 5,000,000
shares of Preferred Stock of the Corporation authorized in Article FOURTH of the
Certificate of Incorporation (the "Preferred  Stock"), a series of the Preferred
stock  consisting  of 1,037,461  shares,  which series shall have the  following
powers, designations, preferences and relative, participating, optional or other
rights,  and the following  qualifications,  limitations  and  restrictions  (in
addition  to  the  powers,   designations,   preferences,   participations   and
restrictions set forth in the Certificate of Incorporation  which are applicable
to the Preferred Stock):

     Section 1. Designation and Amount.

     The shares of such  series  shall be  designated  as "Series A  Convertible
Preferred Stock" (the "Series A Preferred  Stock") and the authorized  number of
shares constituting such series shall be 1,037,461.  The par value of the Series
A Preferred Stock shall be $.001 per share.

     Section 2. Dividends.

     The holders of shares of the Series A Preferred  Stock shall be entitled to
receive, when, as and if dividends are declared by the Board of Directors on the
Corporation's  Common Stock, $.001 par value (the "Common Stock"),  out of funds
of the Corporation legally available  therefor,  cash dividends in an amount per
share of Series A  Preferred  Stock  equal to two  hundred  and fifty  times the
amount  declared  with  respect  to each share of the  Common  Stock.  Each such
dividend  shall be paid to the  holders  of record of the shares of the Series A
Preferred  Stock as they appear on the stock records of the  Corporation  on the
record date for payment of the corresponding dividend on the Common Stock.

     Section 3. Voting Rights.

     The holders of Series A Preferred Stock shall be entitled to vote, together
with the  holders of Common  Stock,  on all  matters as to which  holders of the
Common  Stock shall be entitled to vote,  with the holders of Series A Preferred
Stock being entitled to cast two hundred and fifty votes for each share

                                       B-1




of Series A  Preferred  Stock held by them.  The  holders of Series A  Preferred
Stock shall not be entitled to vote separately, as a class, on any matter except
(a) as provided in Section 7 and (b) as required by law.

     Section 4. Liquidation Rights.

     (a) In the  event of any  liquidation,  dissolution  or  winding  up of the
affairs of the  Corporation,  whether  voluntary or otherwise,  after payment or
provision for payment of the debts and other liabilities of the Corporation, the
holders of shares of the Series A Preferred  Stock shall be entitled to receive,
in cash, out of the remaining net assets of the Corporation,  the amount of $.01
for each share of the  Series A  Preferred  Stock  held by them,  plus an amount
equal to all  dividends  accrued  and  unpaid on each such  share up to the date
fixed for distribution,  before any distribution shall be made to the holders of
shares of Common Stock.  If upon any  liquidation,  dissolution or winding up of
the  Corporation,  the assets  distributable  among the holders of shares of the
Series A Preferred  Stock are  insufficient to permit the payment in full to the
holders  of all such  shares of all  preferential  amounts  payable  to all such
holders,  then the entire assets of the Corporation thus distributable  shall be
distributed  ratably  among the  holders of the shares of the Series A Preferred
Stock in proportion to the respective amounts that would be payable per share if
such assets were sufficient to permit payment in full.

     (b) For  purposes  of this  Section  4, a  distribution  of  assets  in any
dissolution,  winding up or liquidation  shall not include (i) any consolidation
or  merger  of the  Corporation  with or into any  other  corporation,  (ii) any
dissolution,  liquidation,  winding  up or  reorganization  of  the  Corporation
immediately  followed by reincorporation of another  corporation or (iii) a sale
or other disposition of all or substantially all of the Corporation's  assets to
another corporation;  provided, however, that, in each case, effective provision
is made in the  certificate  of  incorporation  of the  resulting  and surviving
corporation  or  otherwise  for the  protection  of the rights of the holders of
shares of the Series A Preferred Stock.

     (c) After the payment of the full preferential  amounts provided for herein
to the holders of shares of the Series A Preferred  Stock or funds necessary for
such payment have been set aside in trust for the holders thereof,  such holders
shall be entitled to no other or further  participation  in the  distribution of
the assets of the Corporation.

     Section 5. Conversion.

     (a) Holders of shares of the Series A Preferred Stock shall have the right,
exercisable  (subject to the  provisions  of Section  5(d)) at any time and from
time to time, to convert each share of Series A Preferred Stock into two hundred
and fifty shares of the Common Stock,  subject to adjustment as described below.
Upon conversion, no adjustment or payment will be made for dividends, but if any
holder  surrenders a share of the Series A Preferred Stock for conversion  after
the close of business on the record date for the payment of a dividend and prior
to the  opening  of  business  on the  payment  date  for such  dividend,  then,
notwithstanding  such conversion,  the dividend payable on such dividend payment
date  will be paid to the  registered  holder  of such  share  of the  Series  A
Preferred Stock on such record date.

     (b) Any  holder  of a share  or  shares  of the  Series A  Preferred  Stock
electing  to convert  such share or shares  shall  deliver  the  certificate  or
certificates  therefor to the  principal  office of any  transfer  agent for the
Common Stock, with such form of notice of election to convert as the Corporation
shall  prescribe  fully completed and duly executed and (if such required by the
Corporation

                                       B-2




or any  conversion  agent)  accompanied  by  instruments  of  transfer  in  form
satisfactory to the Corporation  and to any conversion  agent,  duly executed by
the  registered  holder or his duly  authorized  attorney,  and transfer  taxes,
stamps or funds therefor or evidence of payment thereof if required  pursuant to
Section 5(c) hereof.  The conversion right with respect to any such shares shall
be deemed  to have  been  exercised  at the date  upon  which  the  certificates
therefor accompanied by such duly executed notice of election and instruments of
transfer and such taxes,  stamps,  funds, or evidence of payment shall have been
so  delivered,  and the person or persons  entitled to receive the shares of the
Common Stock issuable upon such conversion  shall be treated for all purposes as
the record holder or holders of such shares of the Common Stock upon said date.

     (c) If a holder converts a share or shares of the Series A Preferred Stock,
the Corporation  shall pay any  documentary,  stamp or similar issue or transfer
tax due on the issue of Common Stock upon the conversion.  The holder,  however,
shall  pay to the  Corporation  the  amount  of any tax  which is due (or  shall
establish to the satisfaction of the Corporation  payment thereof) if the shares
are to be issued in a name other  than the name of such  holder and shall pay to
the Corporation any amount required by the last sentence of Section 5(a) hereof.

     (d) The Series A Preferred Stock shall not become  convertible  into shares
of Common  Stock  until such time as the  number of shares of the  Corporation's
authorized and unissued  Common Stock equals or exceeds the aggregate  number of
shares of the Common Stock into which all of the  authorized  shares of Series A
Preferred Stock would be convertible  under Section 5(a) (without regard to this
sentence)  if all of such shares of Series A Preferred  Stock were  outstanding.
Thereafter,  the Corporation  shall reserve and shall at all times have reserved
out of its authorized but unissued shares of the Common Stock sufficient  shares
of the Common Stock to permit the conversion of the then  outstanding  shares of
the Series A  Preferred  Stock.  All shares of Common  Stock which may be issued
upon  conversion  of shares of the  Series A  Preferred  Stock  shall be validly
issued,  fully paid and  nonassessable.  In order that the Corporation may issue
shares of the Common Stock upon  conversion  of shares of the Series A Preferred
Stock, the Corporation  will endeavor to comply with all applicable  Federal and
State  securities laws and will endeavor to list such shares of the Common Stock
to be issued upon  conversion  on each  securities  exchange on which the Common
Stock is listed.

     (e) The  conversion  rate  in  effect  at any  time  shall  be  subject  to
adjustment from time to time as follows:

          (i) In case the Corporation  shall (1) pay a dividend in shares of the
     Common Stock to holders of the Common  Stock,  (2) make a  distribution  in
     shares of the Common Stock to holders of the Common  Stock,  (3)  subdivide
     the outstanding  shares of the Common Stock into a greater number of shares
     of the Common  Stock or (4)  combine the  outstanding  shares of the Common
     Stock into a smaller  number of shares of the Common Stock,  the conversion
     rate immediately  prior to such action shall be adjusted so that the holder
     of any shares of the Series A Preferred  Stock  thereafter  surrendered for
     conversion  shall be entitled to receive the number of shares of the Common
     Stock which he would have owned immediately  following such action had such
     shares of the Series A Preferred  Stock been  converted  immediately  prior
     thereto.  An adjustment  made pursuant to this Section 5(e)(i) shall become
     effective  immediately  after the record  date in the case of a dividend or
     distribution  and shall become  effective  immediately  after the effective
     date in the case of a subdivision or combination.


                                       B-3




          (ii) In case  the  Corporation  shall  issue  rights  or  warrants  to
     substantially  all holders of the Common Stock entitling them (for a period
     commencing no earlier than the record date for the determination of holders
     of Common  Stock  entitled to receive  such rights or warrants and expiring
     not more than 45 days after such record date) to subscribe  for or purchase
     shares of the Common Stock (or  securities  convertible  into shares of the
     Common  Stock) at a price per share less than the current  market price (as
     determined pursuant to Section 5(e)(iv)) of the Common Stock on such record
     date, the number of shares of the Common Stock into which each share of the
     Series A Preferred Stock shall be convertible shall be adjusted so that the
     same shall be equal to the number  determined by multiplying  the number of
     shares of the Common Stock into which such shares of the Series A Preferred
     Stock was convertible  immediately  prior to such record date by a fraction
     of which the  numerator  shall be the number of shares of the Common  Stock
     outstanding on such record date plus the number of additional shares of the
     Common Stock offered (or into which the  convertible  securities so offered
     are  convertible),  and of which  the  denominator  shall be the  number of
     shares of the Common Stock outstanding on such record date, plus the number
     of shares of the Common  Stock which the  aggregate  offering  price of the
     offered  shares of the Common Stock (or the aggregate  conversion  price of
     the  convertible  securities  so offered)  would  purchase at such  current
     market price.  Such adjustments  shall become effective  immediately  after
     such record date.

          (iii) In case the Corporation  shall  distribute to all holders of the
     Common  Stock  shares of any class of capital  stock  other than the Common
     Stock,  evidence of indebtedness or other assets (other than cash dividends
     out of current or retained earnings),  or shall distribute to substantially
     all  holders  of the Common  Stock  rights or  warrants  to  subscribe  for
     securities (other than those referred to in Section 5(e)(ii)), then in each
     such case the number of shares of the Common Stock into which each share of
     the Series A Preferred Stock shall be convertible shall be adjusted so that
     the same shall equal the number  determined  by  multiplying  the number of
     shares of the Common Stock into which such shares of the Series A Preferred
     Stock was convertible immediately prior to the date of such distribution by
     a  fraction  of which  the  numerator  shall be the  current  market  price
     (determined  as provided in Section  5(e)(iv))  of the Common  stock on the
     record date mentioned  below,  and of which the  denominator  shall be such
     current  market price of the Common Stock,  less the then fair market value
     (as  determined by the Board of  Directors,  whose  determination  shall be
     conclusive evidence of such fair market value) of the portion of the assets
     so distributed or of such subscription rights or warrants applicable to one
     share  of  the  Common  Stock.   Such  adjustment  shall  become  effective
     immediately  after the record date for the  determination of the holders of
     the Common Stock entitled to receive such distribution. Notwithstanding the
     foregoing,  in the event that the Corporation  shall  distribute  rights or
     warrants (other than those referred to in Section  5(e)(ii)  ("Rights") pro
     rata to holders of the Common Stock, the Corporation may, in lieu of making
     any adjustment pursuant to this Section 5(e)(iii), make proper provision so
     that each holder of a share of Series A Preferred  Stock who converts  such
     share  after  the  record  date  for  such  distribution  and  prior to the
     expiration  or  redemption  of the Rights shall be entitled to receive upon
     such  conversion,  in addition to the shares of the Common  Stock  issuable
     upon such conversion (the  "Conversion  Shares"),  a number of Rights to be
     determined  as follows:  (i) if such  conversion  occurs on or prior to the
     date for the  distribution to the holder of Rights of separate  certificate
     evidencing

                                       B-4




     such Rights (the "Distribution Date"), the same number of Rights to which a
     holder of a number of shares of the  Common  Stock  equal to the  number of
     Conversion  Shares is entitled at the time of such conversion in accordance
     with the terms and provisions of and applicable to the Rights;  and (ii) if
     such  conversion  occurs after the  Distribution  Date,  the same number of
     Rights to which a holder of the  number of the  Common  Stock  into which a
     share  of the  Series  A  Preferred  Stock  so  converted  was  convertible
     immediately  prior to the Distribution Date would have been entitled on the
     Distribution  Date in  accordance  with the  terms  and  provisions  of and
     applicable to the Rights.

          (iv) The  current  market  price per share of the Common  Stock on any
     date  shall be deemed to be the  average  of the daily  closing  prices for
     thirty consecutive  trading days commencing  forty-five trading days before
     the day in  question.  The  closing  price  for each day  shall be the last
     reported  sale price  regular way or, in case no such  reported  sale takes
     place on such date,  the  average  of the  reported  closing  bid and asked
     prices  regular way, in either case on the New York Stock  Exchange,  or if
     the Common Stock is not listed or admitted to trading on such Exchange,  on
     the  principal  national  securities  exchange on which the Common Stock is
     listed or  admitted  to trading or, if not listed or admitted to trading on
     any  national  securities  exchange,  the closing  sale price of the Common
     stock, or in case no reported sale takes place,  the average of the closing
     bid and asked prices, on NASDAQ or any comparable  system, or if the Common
     Stock is not quoted on NASDAQ or any  comparable  system,  the closing sale
     price or, in case no reported sale takes place,  the average of the closing
     bid and asked  prices,  as  furnished  by any two  members of the  National
     Association of Securities  Dealers,  Inc. selected from time to time by the
     Corporation for that purpose.

          (v) In any  case  in  which  this  Section  5  shall  require  that an
     adjustment be made immediately following a record date, the Corporation may
     elect to defer (but only until five business days  following the mailing of
     the notice described in Section 5(e)) issuing to the holder of any share of
     the Series A Preferred Stock converted after such record date the shares of
     the Common Stock and other capital stock of the  Corporation  issuable upon
     such  conversion  over and above the shares of the  Common  stock and other
     capital stock of the Corporation  issuable upon such conversion only on the
     basis of the  conversion  rate  prior to  adjustment;  and,  in lieu of the
     shares the issuance of which is so deferred, the Corporation shall issue or
     cause its transfer agents to issue due bills or other appropriate  evidence
     of the right to receive such shares.

     (f) No adjustment in the conversion rate shall be required until cumulative
adjustments result in a concomitant change of 1% or more of the conversion price
as in effect prior to the last  adjustment  of the  conversion  rate;  provided,
however,  that any  adjustments  which by  reason of this  Section  5(f) are not
required  to be made shall be  carried  forward  and taken  into  account in any
subsequent  adjustment.  All calculations  under this Section 5 shall be made to
the nearest cent or to the nearest one-hundredth of a share, as the case may be.
No adjustment to the conversion rate shall be made for cash dividends.

     (g) In the  event  that,  as a result of an  adjustment  made  pursuant  to
Section 5(e), the holder of any share of the Series A Preferred Stock thereafter
surrendered  for  conversion  shall  become  entitled  to receive  any shares of
capital  stock  of the  Corporation  other  than  shares  of the  Common  Stock,
thereafter the number of such other shares so receivable  upon conversion of any
shares of the Series A

                                       B-5




Preferred Stock shall be subject to adjustment from time to time in a manner and
on terms as nearly  equivalent as practicable to the provisions  with respect to
the Common Stock contained in this Section 5.

     (h) The  Corporation  may make such  increases in the  conversion  rate, in
addition to those required by Sections 5(e)(i),  (ii) and (iii), as it considers
to be advisable in order than any event treated for Federal  income tax purposes
as a dividend of stock or stock  rights  shall not be taxable to the  recipients
thereof.

     (i)  Whenever  the  conversion  rate is  adjusted,  the  Corporation  shall
promptly mail to all holders of record of shares of the Series A Preferred Stock
a notice of the adjustment  and shall cause to be prepared a certificate  signed
by a principal  financial officer of the Corporation  setting forth the adjusted
conversion rate and a brief statement of the facts requiring such adjustment and
the computation  thereof;  such  certificate  shall forthwith be filed with each
transfer agent for the shares of the Series A Preferred Stock.

     (j) In the event that:

          (1)  the   Corporation   takes  any  action  which  would  require  an
               adjustment in the conversion rate,

          (2)  the Corporation  consolidates or merges with, or transfers all or
               substantially  all of its  assets  to,  another  corporation  and
               stockholders of the Corporation must approve the transaction, or

          (3)  there is a dissolution or liquidation of the Corporation,

a holder of shares of the Series A Preferred  Stock may wish to convert  some or
all of such shares into shares of the Common Stock prior to the record date for,
or the  effective  date of, the  transaction  so that he may receive the rights,
warrants,  securities  or assets which a holder of shares of the Common Stock on
that date may  receive.  Therefore,  the  Corporation  shall  mail to holders of
shares of the Series A Preferred  Stock a notice stating the proposed  record or
effective date of the transaction,  as the case may be. This  Corporation  shall
mail the notice at least 10 days before such date; however, failure to mail such
notice or any defect  therein  shall not affect the validity of any  transaction
referred to in clauses (1), (2) or (3) of this Section 5(j).

     (k) If any of the following shall occur,  namely: (i) any  reclassification
or change of outstanding  shares of the Common Stock issuable upon conversion of
shares of the Series A Preferred  Stock  (other  than a change in par value,  or
from par  value to no par  value,  or from no par  value to par  value,  or as a
result of a subdivision or  combination),  (ii) any  consolidation  or merger to
which the Corporation is a party other than a merger in which the Corporation is
the continuing corporation and which does not result in any reclassification of,
or change  (other than a change in name,  or par value,  or from par value to no
par value, or from no par value to par value, or as a result of a subdivision or
combination)  in,  outstanding  shares of the Common  Stock or (iii) any sale or
conveyance  of all or  substantially  all of the  property  or  business  of the
Corporation  as  an  entirety,  then  the  Corporation,  or  such  successor  or
purchasing  corporation,  as the case may be, shall, as a condition precedent to
such  reclassification,  change,  consolidation,  merger,  sale  or  conveyance,
provide in its certificate of  incorporation or other charter document that each
share of the Series A Preferred Stock shall be

                                       B-6




convertible  into the kind and  amount  of  shares  of  capital  stock and other
securities and property (including cash) receivable upon such  reclassification,
change,  consolidation,  merger, sale or conveyance by a holder of the number of
shares of the Common  Stock  deliverable  upon  conversion  of such share of the
Series A Preferred Stock  immediately  prior to such  reclassification,  change,
consolidation,  merger, sale or conveyance. Such certificate of incorporation or
other charter  document shall provide for  adjustments  which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Section
5. The foregoing,  however,  shall not in any way affect the right a holder of a
share of the Series A Preferred  Stock may  otherwise  have,  pursuant to clause
(ii)  of the  last  sentence  of  Section  5(e)(iii),  to  receive  Rights  upon
conversion  of a share of the Series A Preferred  Stock.  If, in the case of any
such consolidation,  merger,  sale or conveyance,  the stock or other securities
and property  (including  cash)  receivable  thereupon by a holder of the Common
Stock  includes  shares of capital stock or other  securities  and property of a
corporation other than the successor or purchasing corporation,  as the case may
be, in such consolidation,  merger, sale or conveyance,  then the certificate of
incorporation or other charter document of such other  corporation shall contain
such additional  provisions to protect the interests of the holders of shares of
the Series A Preferred Stock as the Board of Directors shall reasonably consider
necessary by reason of the  foregoing.  The provision of this Section 5(k) shall
similarly apply to successive consolidations, mergers, sales or conveyances.

     Section  6.  Ranking.  With  regard  to  rights to  receive  dividends  and
distributions upon dissolution of the Corporation,  the Series A Preferred Stock
shall  rank prior to the Common  Stock and junior to any other  Preferred  Stock
issued by the  Corporation,  unless  the  terms of such  other  Preferred  Stock
provide otherwise.

     Section  7.  Limitations.  In  addition  to any other  rights  provided  by
applicable  law,  so long as any  shares  of the  Series A  Preferred  Stock are
outstanding,  the Corporation  shall not,  without the affirmative  vote, or the
written consent as provided by law, of the holders of at least a majority of the
outstanding  shares of the Series A Preferred Stock,  voting as a class,  amend,
alter or repeal,  whether  by merger,  consolidation  or  otherwise,  any of the
provisions of the Certificate of  Incorporation  (including this  Certificate of
Designation) that would change the preferences, rights or powers with respect to
the  Series A  Preferred  Stock so as to affect  the  Series A  Preferred  Stock
adversely;  provided,  however, that (except as otherwise required by applicable
law) nothing herein contained shall require such a vote or consent in connection
with any increase in the total number of authorized shares of the Common Stock.

     Section  8. No  Preemptive  Rights.  No holder  of  shares of the  Series A

                             SUBSCRIPTION AGREEMENT

First Medical Corporation
5200 Blue Lagoon Drive
Suite 250
Miami, Florida 33126

Gentlemen:

     The undersigned  ("Subscriber") hereby tenders this Subscription  Agreement
("Agreement')  subject to the terms and conditions set forth herein.  If you are
in agreement, please indicate your acceptance by executing this Agreement in the
space  provided  and  returning  one executed  counterpart  to  Subscriber.  All
references to Subscriber shall include the Subscriber's nominee.

     The  closing of this  transaction  will not occur  until such time as First
Medical  Corporation,  a Delaware  corporation  (the  "Issuer"),  consummates  a
transaction in which it becomes a public company. Accordingly, the parties agree
that all documents to be executed in connection with the  transaction  described
herein  shall be subject to the  closing  of a  transaction  in which the Issuer
shall  become a public  company.  Simultaneously  with the  closing,  the Issuer
agrees to  register  the Common  Stock (as  defined  below)  currently  owned by
Subscriber  and the Common  Stock  purchased by  Subscriber  hereby as described
herein.

     1. Subscription

          1.1 Subscriber  hereby  subscribes for and agrees to purchase a number
     of shares of the Common  Stock,  $.01 par value (the  "Common  Stock"),  of
     First Medical Corporation,  a Delaware corporation (the "Issuer"), equal to
     10% of the issued and  outstanding  Common Stock of the issuer  existing on
     the date of the Closing of the transactions contemplated by this Agreement,
     including the shares issued to Subscriber.

          1.2  Subscriber  hereby  subscribes  for and agrees to  purchase  such
     amount of the 9% Series A Preferred Stock ("Preferred Stock") of the issuer
     as  shall be  convertible  into 10%  shares  of  Common  Stock  issued  and
     outstanding  as at the date of issue.  The  Preferred  Stock  issued to the
     Subscriber  shall form a class of shares of its own.  The  Preferred  Stock
     shall be issued to Subscriber  and shall  contain the terms and  conditions
     set forth in Exhibit "A" annexed hereto and made a part hereof by reference
     and such other terms and  conditions,  if any, as issuer and Subscriber may
     mutually  agree upon in  writing  prior to the  Closing of the  transaction
     contemplated by this Agreement.  As set forth in Exhibit "A," the Preferred
     Stock will pay a 9% cumulative  annual  dividend,  payment of which will be
     deferred until the earlier of (1) the third  anniversary of the Closing and
     (ii) the date of conversion into Common Stock, and will be convertible into
     shares of Common Stock equal to 10% of the currently issued and outstanding
     Common Stock on a fully diluted basis. There will be no new issue of Common
     Stock during 1996.


                                       C-1




          1.3 Subscriber hereby subscribes for and agrees to purchase 49% of the
     issued  and  outstanding  shares of the Common  Stock,  $.01 par value (the
     "WHEN  Common  Stock"),  of  WHEN  Inc.,  a  Delaware   corporation  and  a
     wholly-owned  subsidiary  of the Issuer  ("WHEN").  The WHEN  Common  Stock
     subscribed for hereby equals 49% of the issued and outstanding  WHEN Common
     Stock.

          1.4 The  purchase  price  for the  Common  Stock and  Preferred  Stock
     purchased  hereby is an aggregate of  US$4,000,000.  The purchase price for
     the WHEN Common Stock purchased hereby is US$1,000,000.

          1.5 The Issuer agrees that the proceeds from Subscriber's  purchase of
     the  Common  Stock,  Preferred  Stock and WHEN  Common  (collectively,  the
     "Securities")  shall only be used by the Issuer for the purchase of capital
     assets for WHEN and/or American  Medical Clinics  Development  Corporation.
     Limited, an Irish corporation ("AMCDC").

     2. Restrictions on Transfer.

          2.1 Subscriber  acknowledges  that is acquiring the Securities for its
     own account and for the  purpose of  Investment  and not with a view to any
     distribution  or resale thereof within the meaning of the Securities Act of
     1933, as amended (the "Act"),  and any applicable state or other securities
     laws ("Other Securities Laws").  Subscriber further agrees that it will not
     sell,  assign or transfer any of the Securities so acquired in violation of
     the  Act  or  Other  Securities  Laws  and  acknowledges  that,  in  taking
     unregistered securities,  it must continue to bear the economic risk of its
     investment for an indefinite  period of time because such  Securities  have
     not been  registered  under the Act or Other  Securities  Laws.  Subscriber
     further acknowledges that such Securities cannot be transferred unless they
     are registered under the Act and Other Securities Laws or an exemption from
     such registration is applicable to such transfer.

          2.2 Subscriber  acknowledges that appropriate  legends  reflecting the
     status of the Securities  under the Act and Other  Securities  Laws will be
     placed on the face of the  certificates  for such Securities at the time of
     their transfer and delivery,  including,  without limitation, the following
     restrictive legend:

               "The Shares  represented by this  certificate have been
               acquired directly or indirectly from the Issuer without
               being  registered  under the Securities Act of 1933, as
               amended,  or any other applicable  securities laws, and
               are restricted securities as that term is defined under
               Rule 144  promulgated  under the Act.  These shares may
               not  be  sold,  pledged,  transferred,  distributed  or
               otherwise disposed of in any manner ("Transfer") unless
               they are  registered  under the Act and any  applicable
               securities  laws, or unless the request for Transfer is
               accompanied   by  a   favorable   opinion  of  counsel,
               reasonably satisfactory to the Issuer, stating that the
               Transfer  will not result in a violation  of the Act or
               any applicable state securities laws."


                                          C-2




          2.3  Immediately  following  (i) a  transaction  in which  the  Issuer
     becomes a public company and (ii) any conversion by Subscriber,  the Issuer
     agrees to register all shares of the Common  Stock owned by the  Subscriber
     under the Securities Act of 1933, as amended (the "Act"),  on a Form S-3 or
     other appropriate form of registration.  In addition, in the event that the
     Issuer  proposes to register any  securities  (the  "Registration  Shares")
     under the Act, other than pursuant to a registration  statement on Form S-4
     or S-8,  or any  successor  to such  forms,  for the purpose of the sale or
     other transfer of the Registration Shares by Issuer,  Subscriber shall have
     the right to  request  the Issuer to  include  its  shares of Common  Stock
     and/or Preferred Stock, as the case may be, in such registration  under the
     Act  or  any  other  securities  laws;  provided,  however,  that  if  such
     registration is pursuant to an underwritten  initial public offering and in
     the written opinion of the Issuer's managing underwriter for such offering,
     if any, the inclusion of all or a portion of the  Subscriber's  securities,
     when added to the securities being registered by the Issuer and any selling
     shareholder(s) of the Issuer other than the Subscriber,  if any (the "Other
     Stockholders"),  will exceed the maximum number of the Issuer's  securities
     that can be marketed at the price that could otherwise be obtained or would
     otherwise  materially  adversely  affect the offering,  then the Issuer may
     first include i such registration all of the securities the Issuer proposes
     to sell,  and the  number  of the  Subscriber's  securities  and the  Other
     Stockholders'  securities  that may be so included shall be allocated among
     the  Subscriber  and the Other  Stockholders  pro-rata  on the basis of the
     number of shares that are requested to be registered by Subscriber  and the
     Other   Stockholder(s).   The  parties   hereto  agree  that  the  cost  of
     registration of Subscriber's securities shall be borne by the Issuer.

     3. Covenants and Additional Agreements.

          3.1 As set forth above, the shares of Preferred Stock being subscribed
     for hereby  shall be  convertible  into a number of shares of Common  Stock
     equal to ten percent of the issued and  outstanding  Common Stock of Issuer
     as of the date of issuance.

          3.2  Subscriber  shall have the right to designate half of the members
     of the board of directors of WHEN.

          3.3 The Executive  Committees of the Issuer and WHEN shall include its
     Chairman  of the Board,  its Chief  Executive  Officer  and a  designee  of
     Subscriber  (in the event  Subscriber  shall  select such a  designee)  All
     capital business investments (but not normal capital expenditures) shall be
     approved only by a unanimous vote of their respective Executive Committees.
     Meetings  of the  Executive  Committees  may be  held  by  telephone,  with
     confirmation of votes by fax.

          3.4 At any time within  three (3) years  following  the  Closing,  the
     Subscriber  shall have the option to put the write of its  shareholders  in
     WHEN to the Issuer for the  consideration  of an aggregate of  US$1,000,000
     and a sum  equivalent  to the fair market  value of such  shares.  The fair
     market  value of such  shareholdings  shall be  determined  by a  reputable
     investment banking firm to be selected by the Issuer and the Subscriber. In
     the event the parties  cannot agree on an  investment  banker,  the parties
     shall each select a reputable  investment  banking firm and such investment
     banking  firms shall select a third  reputable  investment  banking firm to
     determine the fair market value of the WHEN Common Stock. The determination
     of the third  investment  banking firm shall be binding upon the Issuer and
     Subscriber.


                                       C-3




          3.5  In  connection  with  the   transactions   contemplated   hereby,
     Subscriber  shall sell to the Issuer,  for  consideration  of  US$1.00,  an
     amount equal to one percent of the shares of AMCDC.  Alain  Leilouche shall
     become Chairman of the Board of AMCDC.

          3.6 It is  understood  by the  Issuer  and  the  Subscriber  that  all
     hospital management contractual agreements will be effected through WHEN.

          3.7 At any time  between the second and the fifth  anniversary  of the
     Closing,  Subscriber  may  acquire  from WHEN that number of shares of WHEN
     Common  Stock  as may be  sufficient,  together  with the  shares  acquired
     pursuant to this  Agreement,  to provide  Subscriber with 52% of the issued
     and  outstanding  common stock of WHEN,  WHEN shall enter into a management
     agreement with the issuer or its wholly-owned subsidiary or other designee,
     pursuant  to  which  WHEN  pays  such  entity,  for two  years  after  such
     acquisition,  an annual  management  fee equal to the sum of WHEN's cost of
     management and a reasonable  success fee to be determined by the issuer and
     the Subscriber.  In the event that Subscriber acquires the additional 3% of
     WHEN Common  Stock,  Issuer will receive from  Subscriber,  at the Issuer's
     option,  either (i) 10% of the  Common  Stock of FMC that was issued at the
     Closing  or  (ii)  US$3,000,000.   Further,   if  Subscriber  acquires  the
     additional  3% of the WHEN  Common  Stock,  Subscriber  will  also have the
     option to purchase at that time the  remaining  shares of WHEN Common Stock
     at a price equal to its fair market  value,  as determined by one reputable
     investment  banking firm, to be selected by the Issuer and  Subscriber.  In
     the event the parties  cannot agree on an  investment  banker,  the parties
     shall each select a reputable  investment  banking  firm who shall select a
     third reputable  investment banking firm to determine the fair market value
     of the WHEN Common Stock. The determination of the third investment banking
     form  shall be  binding  upon the  Issuer  and  Subscriber.  If  Subscriber
     acquires all of the WHEN Common Stock, the management  agreement  described
     in this Section 3.7 shall terminate.

          3.8 Upon the Closing,  the provision of that certain  agreement  dated
     January 20, 1996,  among the Issuer,  the  Subscriber and AMCDC relating to
     the loan by Subscriber of US$1,200,000 shall terminate and be of no further
     force and effect.

          3.9 Subscriber may acquire from Issuer for US$1.00 consideration, that
     number  of  shares of the  Common  Stock of  AMCDC,  par value of the AMCDC
     Common Stock (the "AMCDC Common Stock") as may be sufficient, together with
     the shares of AMCDC Common Stock  already owned by  Subscriber,  to provide
     Subscriber with 52% of the issued and outstanding AMCDC Common Stock.

          3.10 At any  time  prior  to the  fifth  anniversary  of the  Closing,
     Subscriber shall have the option to acquire from the Issuer,  for the price
     of 110% of the average 30-day telling market price thereof,  that number of
     shares of Common  Stock of the  Issuer  that,  together  with the shares of
     Common Stock already held by Subscriber,  shall equal 51% of the issued and
     outstanding Common Stock of the issuer.

          3.11  The  Issuer  and  Subscriber  agree  that  in  exchange  for the
     Subscriber's  termination  of that certain  option granted to Subscriber by
     American  Medical  Clinics,  Inc. ("AMC") and its successor entity American
     Medical Centers Management Company,  Inc., a wholly owned subsidiary of the
     Issuer, which option entitles the Subscriber to purchase, at any time prior
     to December 31,  1997,  10% of the issued and  outstanding  common stock of
     AMC, the Issuer  shall issue  Subscriber a number of shares of Common Stock
     equal to 5% of the issued and outstanding Common Stock of the issuer

                                       C-4




     existing immediately  following the date of the Closing of the transactions
     contemplated  by this  Agreement.  Issuer  agrees that the shares of Common
     Stock issuable to the Subscriber pursuant to this Section 3.11 shall not be
     diluted  during the remainder of the year ended  December 31, 1996,  absent
     agreement between the issuer and the Subscriber.

     the Issuer's  Board of Directors.  Subscriber  shall also have the right to
     appoint a Deputy Chief Financial  Officer to be employed by the Issuer,  as
     well as a Deputy Managing Director of WHEN, to be employed by WHEN.

Dear Sirs:

Reference is made to the Subscription  Agreement (the "Subscription  Agreement")

First Medical  Corporation  ("FMC") pursuant to which GDS will acquire shares of
common  stock,  $.01 par  value  per  share,  of FMC and  shares  of 9% Series A

contemplated by the Subscription Agreement.

We understand  that FMC and The Lehigh Company  ("Lehigh")  have entered into an
Agreement  and Plan of Merger dated as of October 29, 1996,  pursuant to which a
subsidiary  of Lehigh  will merge with and into FMC (the  "Merger").  We further

GDS will  acquire  shares of common  stock,  $.001 par value per share  ("Lehigh

GDS hereby  notifies  FMC and Lehigh  that the  shares of Lehigh  Common  Stock,

as its right to designate a member of the Executive Committee of each of FMC and
FMC Healthcare  Services,  Inc., a Deputy Chief  Financial  Officer of FMC and a
Deputy Managing Director of FMC Healthcare  Services,  Inc. GDS further notifies
FMC and Lehigh that GSD does not have any  intentions,  plans or proposals  that
may relate to or would result in:
    

(a)  Conversion  of any  shares  of FMC 9%  Series A  Preferred  Stock or Lehigh
     Preferred  Stock acquired upon  consummation  of the Merger and the Closing
     into shares of Lehigh Common Stock;


                                       D-1

Member treated by Provider or any other person covered by this provision  within
ten (10) days of the first (1st) day of  treatment.  This clause  shall  survive
termination  or  expiration  of this  Agreement  for a period of six (6)  months
regardless of cause giving rise to termination.

     25. Off-Set

                       SERVICES TO BE PROVIDED TO MEMBERS
                       ASSIGNED TO PRIMARY CARE PROVIDERS

     Provider  agrees to provide or arrange for Covered  Services to Members who
have been assigned to Provider by Humana.  Provider  further agrees not to close
their practice to new Members without prior written  approval of Humana and will
accept  Members  who are  assigned to the  Provider  without  discrimination  or
screening of such Members based upon their health status.

     Covered Services are those services  provided under health benefit plans or
health care contracts  offered,  underwritten,  or  administered  by Humana,  as
specified in the Manual.  Covered  Services include the services of Primary Care

contracted and  credentialed  physicians with Humana.  Provider will also ensure
that the physician  providing coverage renders services under the same terms and
conditions and in compliance with all provisions of this Agreement.

     In the event that emergency and urgent care services are needed by a Member
outside  the  service  are,  the  Provider   shall  monitor  and  authorize  the
out-of-area  care and shall provide direct care as soon as the Member is able to
return to the service area for treatment  without medically harmful or injurious
consequences.

     C.  Provider  shall be capitated  for the  provision  of these  services as

                                       E-8




                     SERVICES TO BE PROVIDED TO MEMBERS NOT

     For  Members  under  health  benefit  or  health  care  contracts  offered,

                                  ATTACHMENT C

                        PAYMENT ARRANGEMENTS FOR MEMBERS
                          ASSIGNED TO PROVIDER'S CENTER

                               COMMERCIAL MEMBERS

     Humana agrees to pay Provider for Covered  Services  provided to Commercial
Members who have been  assigned to Provider's  Center,  according to the payment
arrangement set forth below.

1. Part A Fund

     A Part A Fund  shall be  established  which  will  consist  of the  "Part A
Revenue,"  "Part A  Expenses,"  and  "Claims  Reserve  Fund."  The fund shall be
calculated as follows:

Part A Revenue

     An amount equal to the product of the capitation for each age/sex  category
listed on Exhibit C-1, Commercial Capitations (column titled "HOSP"), multiplied
by the number of Members in each  category,  will be credited to the Part A Fund
as "Part A Revenue."

Part A Expenses

     An amount equal to the claim paid by Humana,  plus a calculated  amount for
claims  incurred  but not  reported or paid (IBNR) for Part A Expenses,  will be
charged to the Part A Fund as "Part A Expenses."

     Part A Expenses  include,  but are not limited  to,  costs  identified  for
inpatient hospital medial and surgical services,  inpatient hospital psychiatric
services,   selected   outpatient   surgery   procedures  at  Humana  contracted
facilities, skilled nursing home services, and home health care services. Part A
Expenses also include the Supplemental Benefits capitation, the cost of the Stop
Loss Pool (as specified in Section 5 below) and other Covered  Services or costs
which may be  determined to be Part A Expenses by Humana in the normal course of
business.

Claims Reserve Fund

     The balance of the Claims Reserve Fund is determined by multiplying the Per
Capita  Reserve  Amount  by the  number of  Commercial  and  individual  Members
currently assigned to the Provider,  and is adjusted on a monthly basis. The Per
Capita Reserve Amount is calculated by dividing the total claims paid,  pending,
or incurred during the prior three months of operation,  by the Provider's total
Commercial and individual enrollment for the same period.

     Surpluses from the Provider's  Part A Fund are paid into the Claims Reserve
Fund each month until the Claims  Reserve  Fund  balance is reached.  The Claims
Reserve Fund shall be used to pay for any Part A Expenses  which are not covered
by the Part A Fund. Any funds remaining upon termination of this Agreement shall
be shared equally between Provider and Humana.


                                      E-10




     Part A  Revenue,  less Part A  Expenses  shall be  calculated  on a monthly
basis,  beginning with the fourth month of this  Agreement.  If the  calculation
reflects a positive balance, then the balance is a surplus. The surplus shall be
credited towards the Claims Reserve Fund balance,  and any net surplus exceeding
the Claims  Reserve Fund balance shall be shared  equally  between  Provider and
Humana. The Provider's share of the net surplus shall be paid to the Provider on
or about the last day of the month following the calculation above.

     If the  calculation  reflects a  negative  balance,  then the  balance is a
deficit.   Fifty-percent  of  the  deficit  shall  be  absorbed  by  Humana  and
fifty-percent of the deficit shall be payable by Provider to Humana.

2. Part B Fund

     A Part B Fund shall be  established  to pay for Part B  Expenses.  The fund
shall be calculated as follows:

Part B Revenue

     An amount equal to the product of the capitation for each age/sex  category
listed on Exhibit C-1, Commercial  Capitation (column titled "REF"),  multiplied
by the number of Members in each category; plus,

     An amount for Supplemental Benefits as listed on Exhibit C-1 (column titled
"Drug" and "Vision"), multiplied by the number of Members who have selected such
supplemental benefits, will be allocated to the Part B Fund as "Part B Revenue."

Part B Expenses

     An amount equal to the claims paid by Humana,  plus a calculated amount for
claims incurred but not reported or paid (IBNR) for Part B costs which Humana is
expected to pay; plus

     An amount allocated to the Stop Loss Pool, plus

     An amount  allocated to the Maternity  Pool,  will be charged to the Part B
Fund as "Part B Expenses."

     Part B Expenses  are all costs for Covered  Services  not defined as Part A
Expenses.  Part B Expenses  include,  but may not be limited to,  hospital based
physician fees,  specialists fees, hospital outpatient services and supplemental
benefits costs.

     Part B Revenue,  less Part B  Expenses,  shall be  calculated  on a monthly
basis,  beginning with the fourth month of this  Agreement.  If the  calculation
reflects a positive  balance then the balance is a surplus.  One Hundred Percent
(100%) of the surplus shall be credited to the Provider on a monthly  basis.  If
the  monthly  calculation  reflects a negative  balance,  then the  balance is a
deficit.  One  Hundred  Percent  (100%) of the  deficit  amount  will be owed by
Provider to Humana.


                                      E-11




3.  Payment of Surpluses or Deficits

     At the close of each month,  any Part A and/or  Part B  surpluses  shall be
offset by any Part A and/or Part B deficits.  Any resulting net surplus shall be
paid to the Provider on or about the end of the following  month.  Any resulting
net  deficit  shall  be paid to  Humana  upon  notification  by  Humana  of such
deficits.

4. Primary Care Capitation

     The Primary Care Capitation paid to Provider for Physician  Services,  will
be  mailed  on or about  the 15th day of each  month,  and will  consist  of the
following:

     An amount equal to the product of the capitation for each age/sex  category
on Exhibit C-1, Commercial  Capitation (column titled "PCP"),  multiplied by the
number of Members in each category.

5. Stop Loss Pool

     A Stop Loss Pool shall be  maintained to pay for Part A and Part B Expenses
incurred  by a Member  after  having  reached  the  threshold  amount in any one
calendar year. Threshold amounts are defined in the Manual.

     Claims paid from the Maternity  Pool shall not be  considered  expenses for
purposes of the Stop Loss Pool, and shall not be included in the calculation.

     The per  member  per month  costs of the Stop Loss Pool shall be charged to
the Part A Fund and Part B Fund on a pro-rata basis.  The initial per member per
month rate for a new Provider will be the rate in effect on the  effective  date
of this Agreement. The rate will adjust for all Providers at the same time.

     Humana  retains the right to purchase  Reinsurance  coverage with the funds
from the Stop Loss Pool for the purposes described above.

6. Maternity Pool

     A Maternity  Pool shall be  maintained to cover the cost of all Part A Fund
and Part B Fund  maternity  expenses (as defined in the Manual).  The per member
per month cost of the Maternity Pool shall be charged to the  Provider's  Part A
Fund and Part B Fund on a pro-rata basis.  The initial per member per month rate
for a new  Provider  will be the rate in  effect on the  effective  date of this
Agreement. The rate will adjust for all Providers at the same time.

     Humana  retains the right to purchase  Reinsurance  coverage with the funds
from the Maternity Fund Pool for the purposes described above.

7. Other Pools

     Provider agrees to participate in any other Stop Loss or Risk  Sharing-type
Pool that Humana may create from time to time that, in Humana's  sole  judgment,
helps ensure the financial

                                      E-12




viability of the Health Care Network. Provider will be notified at least 20 days
in advance of any changes in the Stop Loss Pool or other Risk Sharing-type Pool.

8. Capitation Adjustments

     The per member per month  rates used to  calculate  Part A Revenue,  Part B
Revenue,  Supplemental  Benefits  Capitation or Primary Care Capitation,  may be
adjusted  from time to time to  reflect  the  changes  made in the rates paid to
Humana for  Commercial and individual  Members,  changes in benefits  offered to
Members by Humana or any other business reasons.

     Humana agrees to pay Provider for Covered Services  provided to Members who
have been assigned to Provider,  according to the payment  arrangement set forth
below:

1. Part A Fund

     A Part A Fund  shall be  established  which  will  consist  of the  "Part A
Revenue,"  "Part A  Expenses,"  and  "Claims  Reserve  Fund."  The fund shall be
calculated as follows:

Part A Revenue

     An amount equal to the product of the capitation for each age/sex  category
listed on Exhibit C-2,  Medicare  Capitation  (section A titled "Medicare Part A
Capitation"),  multiplied  by the number of Members  in each  category,  will be
credited to the Part A Fund as "Part A Revenue."

Part A Expenses

     An amount equal to the claim paid by Humana,  plus a calculated  amount for
claims  incurred  but not  reported or paid (IBNR) for Part A Expenses,  will be
charged to the Part A Fund as "Part A Expenses."

     Part A Expenses  include,  but are not limited  to,  costs  identified  for
inpatient hospital medical and surgical services, inpatient hospital psychiatric
services,   selected   outpatient   surgery   procedures  at  Humana  contracted
facilities, skilled nursing home services, and home health care services. Part A
Expenses also include the Supplemental Benefits capitation, the cost of the Stop
Loss Pool (as specified in Section 5 below), and other Covered Services or costs
which may be  determined to be Part A Expenses by Humana in the normal course of
business.

Claims Reserve Fund

     The balance of the Claims Reserve Fund is determined by multiplying the Per
Capita Reserve Amount by the number of Medicare  Members  currently  assigned to
the Provider,  and is adjusted on a monthly basis. The Per Capita Reserve Amount
is calculated by dividing the total claims paid, pending, or incurred during the
prior three months of operation, by the Provider's total Medicare enrollment for
the same period.

     Surpluses from the Provider's  Part A Fund are paid into the Claims Reserve
Fund each month until the Claims  Reserve  Fund  balance is reached.  The Claims
Reserve Fund shall be used to pay for any Part A Expenses  which are not covered
by the Part A Fund. Any funds remaining upon termination of this Agreement shall
be shared equally between Provider and Humana.

     Part A  Revenue,  less Part A  Expenses  shall be  calculated  on a monthly
basis,  beginning with the fourth month of this  Agreement.  If the  calculation
reflects a positive balance, then the balance is a surplus. The surplus shall be
credited towards the Claims Reserve Fund balance,  and any net surplus exceeding
the Claims  Reserve Fund balance shall be shared  equally  between  Provider and
Humana. The Provider's share of the net surplus shall be paid to the Provider on
or about the last day of the month following the calculation above.


                                      E-14




     If the  calculation  reflects a  negative  balance,  then the  balance is a
deficit.   Fifty-percent  of  the  deficit  shall  be  absorbed  by  Humana  and
fifty-percent of the deficit shall be payable by Provider to Humana.

2. Part B Fund

     A Part B Fund shall be  established  to pay for Part B  Expenses.  The fund
shall be calculated as follows:

Part B Revenue

     An amount equal to the product of the capitation for each age/sex  category
listed on Exhibit C-2,  Medicare  Capitation  (section B titled "Medicare Part B
Referral  Capitation"),  multiplied  by the number of Members in each  category;
plus,

     An amount for  Supplemental  Benefits as listed on Exhibit  C-2  (section D
titled "Medicare Supplemental Benefits Capitation"), multiplied by the number of
Members who are eligible for Medicare, Part A.

Part B Expenses

     An amount equal to the claims paid by Humana,  plus a calculated amount for
claims incurred but not reported or paid (IBNR) for Part B costs which Humana is
expected to pay; plus

     An amount allocated to the Stop Loss Pool.

     Part B Expenses  are all costs for Covered  Services  not defined as Part A
Expenses.  Part B Expenses  include,  but may not be limited to,  hospital based
physician fees,  specialists fees, hospital outpatient services and supplemental
benefits costs.

     Part B Revenue,  less Part B  Expenses,  shall be  calculated  on a monthly
basis,  beginning  with the fourth month of the  Agreement.  If the  calculation
reflects a positive  balance then the balance is a surplus.  One Hundred Percent
(100%) of the surplus shall be credited to the Provider on a monthly  basis.  If
the  monthly  calculation  reflects a negative  balance,  then the  balance is a
deficit.  One  Hundred  Percent  (100%) of the  deficit  amount  will be owed by
Provider to Humana.

3.  Payment of Surpluses or Deficits

     At the close of each month,  any Part A and/or  Part B  surpluses  shall be
offset by any Part A and/or Part B deficits.  Any resulting net surplus shall be
paid to the Provider on or about the end of the following  month.  Any resulting
net  deficit  shall  be paid to  Humana  upon  notification  by  Humana  of such
deficits.

4. Primary Care Capitation

     The Primary Care Capitation paid to Provider for Physician  Services,  will
be  mailed  on or about  the 15th day of each  month,  and will  consist  of the
following:


                                      E-15




     An amount equal to the product of the capitation for each age/sex  category
on Exhibit C-2,  Medicare  Capitation  (section C titled "Medicare  Primary Care
Provider Capitation"), multiplied by the number of Members in each category.

5. Stop Loss Pool

     A Stop Loss Pool shall be  maintained  to pay for  expenses  incurred  by a
Member  after having  reached the  threshold  amount.  The  threshold  amount is
defined in the Manual.  The per Member per month rate for a new Provider will be
the rate in effect on the effective date of the contract and will be revised for
all Providers at the same time. Humana retains the right to purchase reinsurance
coverage for these purposes.

6. Other Pools

     Provider agrees to participate in any other Stop Loss or Risk  Sharing-type
Pool that Humana may create from time to time that, in Humana's  sole  judgment,
helps ensure the financial  viability of the Health Care Network.  Provider will
be  notified at least 30 days in advance of any changes in the Stop Loss Pool or
other Risk Sharing-type Pool.

8. Capitation Adjustments

     The per member per month  rates used to  calculate  Part A Revenue,  Part B
Revenue,  Supplemental  Benefits  Capitation or Primary Care Capitation,  may be
adjusted  from time to time to  reflect  the  changes  made in the rates paid to
Humana for  Commercial and individual  Members,  changes in benefits  offered to
Members by Humana or any other business reasons.

                                      E-16




            PAYMENT ARRANGEMENT FOR MEMBERS NOT ASSIGNED TO PROVIDER

1. Humana P.P.O.  and other  non-assigned  Members (except  Medicare  Supplement
   Members)

     As of the Effective Date, for those Members who are under health benefit or
health care contracts  offered,  underwritten,  or  administered by Humana where
Members are not assigned to Provider,  Provider  agrees to provide all physician
services offered by Provider.  Provider agrees to accept as payment in full from
Humana  seventy  percent  (70%) of the  Medicare  Allowable  or  Provider's  Fee
Profile,  whichever is less,  less any co-payments and deductibles due from such
Members for  physician  services  provided to such Members (the "Fee for Service
Payment Method").

2. Humana Medicare Supplement Members

     As  of  Effective   Date,   Provider  also  agrees  to  bill  the  Medicare
intermediary,  for Humana  supplemental  benefit plans where  Humana's  coverage
supplements the basic coverage of another carrier or third party payor. Provider
agrees to accept the basic coverage as payment in full.

                                      E-17




                                  ATTACHMENT D

                              DURATION OF AGREEMENT

     This  Agreement  shall  continue  for a term of five  (5)  years  from  the
effective date, unless terminated as provided in this Agreement.

     Provider may  terminate  this  Agreement  for cause if Humana fails to make
payments  required  under  this  Agreement,  but only after  written  notice and
providing  at least  sixty (60) days in which  Humana may avoid  termination  by
curing the default in payment. Any dispute concerning the amount of payment owed
shall be resolved according to the procedures specified in the Manual.

     Humana may terminate  this  Agreement for cause if Provider  fails to carry
out any term or condition of this  Agreement or has  otherwise  defaulted  under
this Agreement,  after thirty (30) days written  notice,  or Humana may elect to
impose  optional  procedures  in  lieu of  termination  of  this  Agreement,  as
specified in this Attachment D.

     Humana may  terminate  this  Agreement  immediately  upon  written  notice,
stating  the  cause  for  such  termination,  in  the  event  Humana  reasonably
determines that (i) Provider's continued  participation under this Agreement may
adversely affect the health,  safety or welfare of any Member or bring Humana or
its  health  care  networks  into  disrepute,  (ii) or  Provider  engages  in or
acquiesces to any act of bankruptcy,  receivership or  reorganization,  (iii) or
Humana  loses its  authority  to do  business.  Humana may also  terminate  this
Agreement  immediately if it loses  authority to conduct any limited  segment of
its business, but only as to that segment.

     Humana may elect to terminate  this  Agreement  upon sixty (60) day written
notice, if Provider's  cumulative Part A/Part B deficits,  for three consecutive
months,  exceeds  those  months'  cumulative  Primary Care  Capitation  by 100%.
"Cumulative"  Deficit  is  defined as the  amount of the  deficit  after  offset
payments (offset provisions are defined in Clause 25). "Cumulative" Primary Care
Capitation  is defined as the  Provider's  capitation  amount for  Primary  Care
Services net any offset  payments or  withholds.  Termination  may be delayed or
waived. Waiver for termination for any given period would not waiver termination
rights for succeeding periods.

     Provider  agrees  that  he  will  not  alter  his  referral   patterns  for
non-Members  as a result of entering into this contract or as a result of Humana
entering into any contract with any other  practitioner  (herein the "Referee").
If the percentage of Provider's  non-Members  referred to a Referee  declines by
greater than 10% during any six (6) month period  compared  with the  percentage
referred  prior  to the  Referee's  Effective  Date,  and if  the  Referee  also
contracts  to furnish  services  to  Members,  then  Humana  may, at its option,
terminate  this  Agreement  upon sixty (60) days notice  unless  Provider  shall
submit  evidence  satisfactory  to Humana  that the change in  referrals  to the
Referee  was for a cause  other than  Referee's  entering  into a contract  with
Humana.

     Either party may elect to terminate this Agreement  without cause after the
first two (2) years upon giving six (6) months written notice. In addition, this
Agreement  may be terminated  by mutual  written  consent of both parties at any
time.

     Any termination of this Agreement (except immediate terminations) by either
party, shall become effective at the end of a month. Upon termination,  Provider
agrees to provide medical services

                                      E-18




to any  Member  hospitalized  on the  date  of  termination  until  the  date of
discharge,  or until Humana has made  arrangements for substitute  care.  Humana
agrees to pay for such covered services in accordance with Attachment C.

     Provider  understands  that termination of this Agreement shall not relieve
Provider from Provider's  obligation to provide,  or arrange and pay for Covered
Services to Members through the last day of this  Agreement.  Humana retains the
right to recover  from  Provider any costs paid on  Provider's  behalf which are
obligations  of Provider  and become  necessary to be paid by Humana to maintain
the health care delivery network.

     Compliance  with  Florida  Statutes - As  required  under  Florida  Statute
Section  641.234,  as amended,  effective  October 1, 1988, if the Department of
Insurance has information and belief that this Agreement requires Humana Medical
Plan,  Inc. and/or Humana Health Plan of Florida,  Inc.  ("Humana") to pay a fee
which is unreasonably high in relation to the services provided, after review of
this  Agreement,  the department may order Humana to cancel this Agreement if it
determines  that the  fees to be paid by  Humana  or as  compared  with  similar
contracts  entered into by other  health  maintenance  organizations  in similar
circumstances,  such that this  Agreement  is  detrimental  to the  subscribers,
stockholders,  investors,  or creditors of Humana. The issuance of such an order
by the Florida  Department of Insurance  will not affect the  termination of the
entire  Agreement  which shall  remain in full force and effect with  respect to
Humana Health Insurance  Company of Florida,  Inc. and Humana Insurance  Company
and product lines  contemplated in the Agreement to which this Amendment is made
a part.

     As required under Florida Statute Section  641.315,  Provider shall provide
sixty (60) days advance  written  notice to Humana at the address  listed in the
"Notices" section of this Agreement, and to the Department of Insurance,  Bureau
of Specialty Insurers, 200 East Gaines Street, Tallahassee,  Florida 32399-0300,
before canceling this Agreement with Humana for any reason. Nonpayment for goods
or services  rendered by Provider to Humana or any of its Members shall not be a
valid reason for  avoiding  such 60-day  advance  notice of  cancellation.  Upon
receipt by Humana of a 60-day cancellation  notice,  Humana may, if requested by
the  Provider  terminate  the contract in less than sixty (60) days if Humana is
not financially impaired or insolvent.

     Humana and Provider hereby acknowledge and agree that the provisions stated
in the  previous  paragraph  do not  relieve  the  Provider  of any of its other
obligations  under this Agreement that are not inconsistent  with the foregoing,
including  without  limitation any obligation  Provider has to provide more than
sixty (60) days notice of cancellation of this Agreement, to Humana.

     Any change  (including  any addition  and/or  deletion) to any provision or
provisions of this Agreement that is required by duly enacted federal or Florida
legislation,  or by a regulation or rule finally  issued by a regulatory  agency
pursuant to such legislation,  rule or regulation,  will be deemed to be part of
this Agreement  without  further action  required to be taken by either party to
amend this  Agreement  to effect  such  change or  changes,  for as long as such
legislation, regulation or rule is in effect.

Optional Procedures in Lieu of Termination

     If, upon Humana's  determination  that Provider has breached this Agreement
or is not abiding by any policy or procedure  specified in this  Agreement,  the
Manual,  or other publication by which Provider has been notified of such policy
or procedure, Humana may elect to implement a remedial

                                      E-19




plan under which the Provider  will have a  reasonable  period of time to comply
with  the  provisions  of this  Agreement.  This  "Corrective  Action  Plan"  is
specified in the Manual.

     Humana may also  immediately  implement a procedure to restrict new Members
at Provider's  Medical  Center.  This procedure will continue until such time as
Humana  determines  that  Provider has  corrected  the default and may then take
additional Members.

     If,  as a  result  of  Provider's  untimely  payment  to any  Participating
Provider  which  Provider is obligated to pay directly,  the services of Members
are  disrupted,  Humana may,  at its sole  discretion,  immediately  implement a
procedure in lieu of  termination  whereby  Humana will pay such  providers  and
deduct the payment  from any monies due and owing by Humana to  Providers.  This
procedure will continue until such time as Humana  determines  that the Provider
is able to resume  payment to these  providers  without  disruption of services.
This shall not relieve the Provider's obligation to pay Participating Providers.

     Provider  understands  that  Humana  has no  obligation  to  implement  the
Optional Procedures specified above in lieu of termination, and that such option
does not waive any rights under this Agreement.

                                    SECTION 1
             HEALTH CARE DELIVERY NETWORK - PARTICIPATING PROVIDERS

     Except as otherwise  provided in this  Agreement,  Provider  shall admit or
refer   Members  to  those   hospitals,   specialists   and  other  health  care
professionals,  hereinafter "Humana  Participating  Providers," with whom Humana
has  contracted  as part of its  Health  Care  Delivery  Network.  These  Humana
Participating  Providers  are listed in the  Manual and may change  from time to
time.  Humana  shall  pay  the  Humana  Participating  Providers  directly  at a
pre-negotiated  capitation payment or  fee-for-service  payment on behalf of the
Provider  for  appropriately  referred  services,  and these  payments  shall be
charged to the appropriate  account of the Provider,  as described in Attachment
C.

     Provider may substitute  their own  Participating  Provider with another of
their own choosing after having first obtained written approval of Humana,  such
approval  shall not be  unreasonably  withheld.  Provider  shall obtain  written
agreement  from these  Participating  Providers  after Humana has approved  such
agreements and Participating  Providers have been credentialed by Humana. Humana
will pay these participating providers directly as described above.

     Provider   understands  and  agrees  that  no  physician  or  other  health
professional  or  facility  shall be  permitted  to provide  services  to Humana
Members which have not been  credentialed by Humana.  Provider agrees to replace
any physician or other health professional who has been decredentialed by Humana
within a reasonable  period of time after  Provider has been notified in writing
of such decredentialing, with a provider who has been credentialed by Humana.

     Provider  understands  that, from time to time, other providers'  agreement
will expire or be terminated, and that Members will be transferred to Provider's
Center. Provider agrees to honor existing Health Care Delivery Network contracts
covering Members which have been transferred into Provider's Center,  until such
time as those contracts can be terminated.

                                    SECTION 2
                               PROVIDER'S FACILITY

     Provider  is, or will be  providing  health care  services at the  facility
location  listed on the  attached  Attachment  F. This  facility is known as the
Provider's "Center." Provider agrees not to change

                                      E-21




the  location  where  services  are  provided  to  Members,  or to add  any  new
locations,  without the prior written  approval of Humana.  Similarly,  Provider
must obtain  Humana's  prior  written  approval  before  closing  any  location.
Provider will establish  regular business hours for the provision of services to
Humana  Members.  In  establishing  business  hours,  Provider  should take into
consideration  the number  and type of Members  assigned  to the  facility.  The
proposed  business  hours  listed on  Attachment  F are  subject to  approval by
Humana.  This does not relieve Provider of its obligation to provide 24-hour per
day medical coverage for Members.

                                    SECTION 3
                            ADVERTISING AND MARKETING

     Provider may participate in the generation of Membership  through marketing
and advertising only after obtaining prior written approval of Humana.  Provider
will not  advertise  or utilize  any  marketing  materials,  logos,  tradenames,
servicemarks,  or other materials  created or owned by Humana, or make reference
to Humana without Humana's written consent. Provider shall not acquire any right
or title in or to the marketing materials, logos, tradenames,  service marks, or
other  materials  of Humana,  the same shall  remain at all times the  exclusive
property of Humana.

     Provider  agrees to  install  appropriate  signage  promoting  Humana  both
outside and inside its facility,  subject to limitations in Provider's  lease or
local  ordinance.  Such signage must be approved by Humana and will be installed
at Provider's  expense.  Provider further agrees to display marketing  materials
provided by Humana  inside the  facility.  Upon request by Humana and within ten
(10) working days, Provider agrees to remove any such signage and materials from
exterior or interior of its facility,  as the case may be, and either deliver or
destroy same in accordance with the instructions of Humana.

     Provider agrees not to send written  communication  to Provider's  Members,
other  than that  provided  for in the  manual,  without  the prior  review  and
approval by Humana.

                                    SECTION 4
                              CONFLICT OF INTEREST

     Provider  hereby  represents  and  warrants  that,  except as  disclosed on
Attachment  G,  Provider,  including all  Principals  of Provider,  shall not be
interested,  directly or indirectly,  in any manner,  as a contractor,  partner,
officer, director, shareholder,  advisor, employee, or in any other capacity, in
any other health  maintenance  organization,  prepaid  health  plan,  or similar
entity  providing   prepaid  health  services,   hereafter   referred  to  as  a
"Competitive Plan."

     Provider agrees that Provider has a continuing  obligation to notify Humana
of any changes in Attachment G.

     Provider is not  permitted  to contract or affiliate  with any  Competitive
Plan which  offers a Medicare  HMO product  which will be provided to members of
the Competitive Plan at the same facility where services are provided to Members
of Humana.  Provider  may contract or affiliate  with a  Competitive  Plan which
offers  a  Medicare  HMO  product  which  will be  provided  to  members  of the
Competitive  Plan at a facility which is not affiliated with Humana and which is
a  reasonable  distance  from the  Provider's  facility  under  this  Agreement.
Provider may contract or affiliate with a Competitive  Plan which does not offer
a Medicare HMO product at any facility.

                                      E-22




     Humana  reserves  the right to  determine  which  Competitive  Plans  offer
Medicare HMO products and to prohibit  Provider from  contracting or affiliating
with such plans at the facility under this Agreement,  or at facilities within a
reasonable distance from this facility.

     Provider represents and warrants that neither Provider, nor any employee or
agent of Provider,  shall  solicit or otherwise  attempt to induce,  directly or
indirectly, any Members to disenroll from Humana or to enroll in any Competitive
Plan.  It  shall  be  deemed   conclusively  that  Provider  has  breached  this
representation  and warranty if a Member disenrolls from Humana,  and within six
(6) months  thereafter,  or six (6) months  following  any  termination  of this
Agreement,  whichever  shall occur first,  said Member  enrolls in a Competitive
Plan in which Provider is interested, directed or indirectly.

     Provider  agrees to identify any and all facilities and agencies (e.g. Lab,
X-ray,  Nursing  Home or Home  Services  agency,  etc.)  where  Provider  refers
patients and where  Provider has an  ownership or financial  interest.  Provider
will make such disclosure at time of contract execution and thereafter  whenever
ownership or financial interest in a facility or agency is obtained.

     Except in the case of death or legal incompetence,  Provider represents and
warrants that there shall be no change in ownership  without Humana's  approval,
and such  approval  shall  not be  unreasonably  withheld.  Any such  change  in
ownership is subject to the  limitations of Assignment and Delegation  specified
in Article 17 of this Agreement.  In the event a change of ownership occurs as a
result of the death or legal incompetence of one of the Principals, Provider (or
its personal representative) shall notify Humana of any such change or impending
change within  fifteen (15) days of the date of death or petition for a judgment
of incompetence.

                                    SECTION 5
                                 MEDICAL RECORDS

     Provider shall maintain and retain records on behalf of Humana  relating to
Members in such form as required by law and accepted  medical  practice.  Humana
shall be the owner of such  records  and may  obtain,  copy,  have access to, or
cause to be transferred any and all medical, administrative or financial records
related to the covered services provided by Provider to any Member upon request.
Provider  agrees to transfer the original  medical  record of any Member who has
transferred to another  Provider for any reason,  including  termination of this
Agreement, upon request by Humana or the Member. The transfer of medical records
shall be at no cost to either Humana or the Member. Provider agrees to pay court
costs or legal fees necessary for Humana to enforce the terms of this Section 5.
This Section 5 shall survive the termination of this Agreement for any reason.

                                    SECTION 6
                              ACCESS TO INFORMATION

     Provider agrees Humana or its designee shall have access and an opportunity
to thoroughly examine Provider's  facilities,  books,  records and operations at
any time.  Further,  Humana or its designee shall have access and an opportunity
to thoroughly examine at any time facilities,  books,  records and operations of
any related  organization  or entity.  Related  organization  or entity shall be
defined  as (1)  having  influence  or  ownership  or  control  and (2) either a
financial  relationship or a relationship for rendering of services.  Purpose of
such  requirement  is to permit Humana the right to assure  compliance  with all
financial,  operational,  quality  assurance,  as well  as,  any  and all  other
obligations required of Provider under this Agreement or the Manual.

                                      E-23




     Failure by any person or entity  involved,  including  Provider,  to comply
with any requests for access, above mentioned,  within ten (10) business days of
receipt of notification will be considered a breach of contract.
